This research aims to determine the increased learning outcomes in Catholic Religious Education subjects for grade 4 students at SDN 25 Talhut. This research uses a classroom research method carried out in two cycles. Each cycle consists of four stages: planning, implementation, observation, and reflection. The average score students obtained when using the PBL model in the first cycle was 69%, and in the second cycle, it was 85%, according to the research results for the two processes. If the PBL learning model is implemented well and consistently, it will improve student learning outcomes.
